OpenAI: GPT-5 Nano

GPT-5 Nano is OpenAI's lightweight text model that also accepts image and file inputs, giving it practical multimodal reach without requiring a separate pipeline. It supports tool use and reasoning, and its 400,000-token context window handles long documents or extended conversations without truncation. Structured output support is unconfirmed from available data. At $0.05 per million input tokens and $0.40 per million output tokens, this is a cost-oriented option worth shortlisting for high-volume or latency-sensitive workloads where budget discipline matters more than peak performance. Its blended benchmark score of 32.0 is drawn from only one independent benchmark, so treat that figure as preliminary rather than a settled verdict on capability. Teams running straightforward extraction, classification, or summarization tasks at scale will find the pricing attractive, while those needing top-tier reasoning should weigh it against higher-scoring alternatives first.
